HYDRAULICALLY DAMPING ELASTOMER BEARING

Abstract

A hydraulically damping elastomer bearing has at least one housing (1, 2), a connection element (3), an elastomer body (4), which couples the housing (1, 2) and the connection element (3) with one another in a vibration-damping manner. Two chambers (5, 6) filled with a fluid are provided as well as at least one flow channel (8), which connects the chambers (5, 6) to one another. A recess (9) in the housing (1, 3) is associated with the flow channel (8). A valve (10) is present in the recess (9) for opening and closing the flow channel (8). An actuator (11) is provided for actuating the valve (10) on the outside of the housing (1, 2). The valve (10) includes an elastic diaphragm (12), in which an insert (13) is embedded.
